転検出装置。 A ring-shaped magnet is connected to a rotating shaft 6 whose rotational speed is measured in a cylindrical case 10 made of a non-magnetic material, rotates concentrically with the rotation of the shaft 6, and is magnetized with multiple poles on its outer periphery. Along with supporting 13,
In a rotation detecting device, a ring-shaped coil 15 is installed in the coil 15 so that the magnet 13 rotates, and the case 10 is closed with a lid 19 in which a terminal 18 is embedded.
The coil 15 is pressed and fixed to the case 10 by bringing the other ends of two elastic pieces (26 or 26') made of a conductive material fixed to the coil 15 into electrical continuity. Characteristic rotation detection device.
